Moving to the DC area

My wife and I are moving to the DC area in about 2 months and I was just curious as to which towns/neighborhoods are good in Maryland. We're looking primarily in Charles County but I have no clue what the commute is going to be like. I figured what better place to get some real opinions and advice since I recall reading that there are plenty of 11 dubbers in the DC area. Thanks in advance and, as always, Go Bucks!
